Subject: [PATCH 0/3] Fix cross compiling x86 with clang

Hi all,

This series fixes cross compiling x86 with clang, which was initially
brought up by John here:

https://lore.kernel.org/r/cceb074c-861c-d716-5e19-834a8492f245@gmail.com/

I have picked up that patch and added the same fix in a couple of other
places where it is needed.

I have tested this on an ARM based server with both defconfig and
allmodconfig, where the build now passes.

Please let me know if there are any problems.

Cheers,
Nathan
